Patent number: 10116307Abstract: Disclosed herein are system, methods, and apparatus for low power capacitive sensors. Apparatus may include a timing block configured to generate a repetitive trigger signal having a first frequency, and further configured to generate a clock signal having a second frequency. Apparatus may also include a sensing block coupled with the timing block and configured to, in response to the repetitive trigger signal, detect a change in capacitance associated with an object proximate to a capacitive sensor button by applying an excitation signal to the capacitive sensor button during a measurement period. Apparatus further include a wake logic block coupled with the sensing block and configured to transition a processing unit from a first power consumption state to a second power consumption state in response to the sensing block detecting the change in capacitance associated with the object proximate to the capacitive sensor button.Type: GrantFiled: September 25, 2015Date of Patent: October 30, 2018Assignee: Cypress Semiconductor CorporationInventors: Andriy Maharyta, Carl Ferdinand Liepold, Hans Klein
